This study aims at determining factor that influence individuals’ happiness in Turkey. For this purpose, we have built a model that is as broad as possible and have tested this model both in Turkey in general and at the level of cities. The fact that the model uses such variables as social pressure depending on sex and income, indebtedness, satisfaction with government services, satisfaction with the individual's relations with his/her close circle, which are not included in domestic literature, and the fact that it was repeated in 81 provinces are the basic contributions of the study.The study has used the ordinal logistic regression model. According to the model results, it is possible to tell whether individuals in Turkey are happy or unhappy with similar factors in general. Optimistic, female, university-graduate individuals who can have positive relations with their near social environment and who are happy from their marriage, work, health, income, social life and public services, are seen to be happier. Whereas, individuals who are not satisfied from their marriages, unemployed, indebted individuals, crime victims, individuals who feel pressure on themselves because of their sex or income are seen as more unhappy.Applying the model to cities presents some additional data. It becomes possible to observe distribution of cities where variables are statistically meaningful or not meaningful, and in some cases where they are clustered. On the other hand, we have also observed that a positive relationship in overall Turkey analysis, may be negative at city level or vice versa. This observation leads to the necessity of broadening analyses to the city level.
